It wasn't just about pride, Chris Evans' big superhero Super Bowl bet with Chris Pratt helped raise more than $11k for Evans' charity ... TMZ Sports has learmed.
You already know the bet ... Star-Lord and Captain America agreed to visit the other actor's charity IN COSTUME if their team lost the big game.
In the end, both stars decided to visit both charities ... but Evans' organization, Christopher's Haven, tells us they got an unexpected boost from fans looking to pitch in as well.
Joyce Duvall, executive director of Christopher's Haven -- which helps provide housing for families with children fighting pediatric cancer -- tells us the org. received just over $11k from fans.
"The coolest thing about something like this is that all the kids win ... no matter what happened in the football game," Duvall says.
Actually, the coolest thing might be when the actors show up IN COSTUME ... but yeah, the fundraising's cool too.
Nice work, America.
